The 3D Blades of Avernum Editor (3D Editor) is the preferred tool for creating scenarios for Spiderweb Software's open-ended CRPG, Blades of Avernum. Based on the original editor supplied by Spiderweb, it adds new tools and features to make scenario creation easier.

Please note that in order to play scenarios made with the editor it is necessary to have a paid copy of the actual Blades of Avernum game itself. The editor, however, is free software.
